Abstract
The utility model discloses a kind of 3D printing pen and automatically move back silk device.It is in insulation crust, comprising: shell, feed pipe, motor fixing seat, motor, driving wheel (gear), consumptive material, optoelectronic switch, driven pulley (deep groove ball bearing), H bridge drive chip, master controller IO, button.The beneficial effects of the utility model are, can in the time that product is idle, can automatically move back a function to product, reduce human factor (forget or do not press in time move back a key that residue consumptive material is exited to pen is interior) plug nozzle, thereby when having continued to greatest extent service life of product, also reduce the waste of parts, the social value of bringing is thus very high.
Description
Technical field
The utility model belongs to a kind of 3D printing pen and automatically moves back silk device.
Background technology
Chinese patent CN203357906, this patent discloses a kind of traditional 3D and has printed pen, and it is by pressing lower thread-feeding key, extruder motor starts to be docile and obedient clockwise rotation, consumptive material is transported to 3D and prints in pen, then heat by described heater strip, reach preset temperature, make consumptive material fusing, by the pressure of described extruder, consumptive material is sprayed at described shower nozzle, while stopping, then press and move back a key, make extruder motor start, according to counterclockwise rotation, consumptive material to be printed in pen and exited from 3D.
This operating process need to be pressed twice button (enter a key and move back a key) artificially, operates pretty troublesome.Print pen after being used to complete for another this 3D of fruit, forget or not in time (press and move back a key) residue consumptive material is exited in pen, consumptive material long-time heating in a chamber, makes consumptive material high temperature cabonization and blocks nib.And in actual use procedure, the also phenomenon of frequent generating material plug nozzle, cannot keep in repair after plug nozzle, can only change a new nozzle, cause serious waste of resources to a great extent.
Above shortcoming is badly in need of improving.
Summary of the invention
Can not intelligent move back consumptive material silk and often block written deficiency in order to overcome existing 3D printing pen, the utility model not only provides a kind of (button is moved back in cancellation) simple in structure, highly intelligent (consumptive material silk is moved back in intellectuality).Silk is moved back in intellectuality, and (that is: in the time of user's shut-down operation, if user does not operate again in setting-up time, consumptive material will exit automatically in pen, without artificially manually moving back silk.Such benefit is: because of human factor forget or not in time (press and move back a key) residue consumptive material is exited to the plug nozzle causing in pen, this phenomenon will improve to a great extent).
The utility model solves the technical scheme that its technical problem adopts: motor is enclosed within motor fixing seat, and with screw fastening in shell respective screws hole, motor is connected to PCB control panel H bridge and drives on chip, then drives chip to be connected on master controller IO by H bridge.
The right-hand member of motor has an optoelectronic switch, and optoelectronic switch is fixed in upper casing respective screws hole by screw thread.Pcb board is fixed to shell left end with screw line, and optoelectronic switch is connected to the master controller IO on pcb board by connector.In the time that optoelectronic switch photosensitive region has consumptive material to pass through, optoelectronic switch induction is cut off, and this signal is passed to master controller IO, and master controller IO allows user to make to print pen by button and enters duty.In the time that optoelectronic switch photosensitive region no material consumption passes through, optoelectronic switch induction is switched on, this signal will be caught by master controller IO, now master controller IO timer internal starts timing (if no material consumption continues to insert during timing, timing will can not stop), in the time that timing time arrives preset value (10 seconds), timing finishes, controller will drive chip drives motor by H bridge, it is rotated backward, residue consumptive material is exited in pen, complete and automatically move back a function, to prevent material long-time heating in a chamber, make material carbonization and block nib
Motor is direct current generator, and the control module of control panel adopts single-chip microcomputer, and motor module comprises; Direct current generator drives chip, direct current generator socket, control module is connected to direct current generator and drives chip, direct current generator drives chip to be connected to direct current generator socket, direct current generator is connected to direct current generator and drives chip, the motor of control panel enters a button and is connected to control panel keystroke interface module by control panel keystroke interface, is connected to control module. motor just/reversion by control module control motor drive ic, finally control the forward or reverse of motor
The beneficial effects of the utility model are, can in the time that product is idle, can automatically move back a function to product, reduce human factor (forget or do not press in time move back a key that residue consumptive material is exited to pen is interior) plug nozzle, thereby when having continued to greatest extent service life of product, also reduce the waste of parts, the social value of bringing is thus very high.

Detailed description of the invention
As follows with reference to accompanying drawing 1: a kind of 3D prints pen and automatically moves back silk device, comprising: the electrical connection of motor, optoelectronic switch, motor fixing seat and optoelectronic switch/motor, is characterized in that:
Motor (4) is enclosed within motor fixing seat (3), and with screw fastening in shell (1) respective screws hole, motor is connected to main PCB plate H bridge by motor pin (14) and drives the pin (output) of chip (9) upper, then drives the pin (input) of chip (9) to be connected on main PCB plate master controller IO (10) pin (output) by H bridge.
The right-hand member of motor increases an optoelectronic switch (for detection of there being no material consumption to pass through), optoelectronic switch (7) is screwed on upper casing (1) respective screws post, and the switching signal of optoelectronic switch (7) is connected on master controller IO (10) by optoelectronic switch pin (13).
Consumptive material (6) enters to left end from the right-hand member porch (12) of shell (1), in the time that consumptive material (6) passes through optoelectronic switch (7) photosensitive region, the induced signal of optoelectronic switch (7) is cut off, this shutoff signal will be passed to master controller IO (10), now master controller IO (10) response button (11) operation, motor (4) enabling signal is passed to H bridge and drive chip (9), H bridge drives chip (9) drive motors (4) forward rotation (rotating clockwise); Consumptive material (6) is through between driving wheel (5) and driven pulley (8), under the active force of driving wheel (5) and driven pulley (8), continue mobile left, enter translucent feed pipe (2) inside being fixed in motor fixing seat (3) and again continue to be moved to the left, until arrive heating tube.
In the time that optoelectronic switch (7) photosensitive region no material consumption passes through, optoelectronic switch (7) induced signal is switched on, this connection signal will be passed to master controller IO (10), master controller IO (10) timer internal starts timing (if no material consumption continues to insert during timing, timing will can not stop), in the time that timing time arrives preset value (10 seconds), timing finishes, master controller IO (10) will drive chip (9) drive motors (4) to make its oppositely (counterclockwise) rotation by H bridge, residue consumptive material is exited in pen, complete and automatically move back a function, to prevent material long-time heating in a chamber, make material carbonization and block nib.
